Abstract Details


Purpose: 1.To study indications and factors associated with IOL explantation. 2.To compare the indications with the earlier studies. 3.To study the outcomes of IOL explantation.


L.V. Prasad Eye Institute, Bhubaneswar, India


1 Study Setting: This study was conducted at the Retina vitreous Services division at the L.V. Prasad Eye Institute, Patia, Bhubaneswar, Odisha, India. 2 Study Design: Retrospective Case series Retrospective chart review done from June 2007 to August 2014. 3 Study population: Inclusion criteria - All patients requiring IOL explantation. Exclusion criteria - Patients with inadequate records 4 Statistical analysis: Wilcoxon matched-pairs signed-ranks test p less than 0.05 was considered significant


A total of 135 eyes which underwent IOL explantation were studied. Mean age at explantation was 54 years and 75.5% were male. The main cause IOL explantation was dislocation or decentration (74%) followed by endophthalmitis (17.3%). Among the cases with dislocation or decentration of IOL, 15 (11.11%) had retinal detachment. 5.18% of cases had pseudophakic bullous keratopathy as the reason for explantation. There was significant improvement in vision following IOL explantation with an average gain of 7 letters (p less than 0.001). At the last follow up 60 cases (44.44%) were pseudophakic while 75 cases (53.55%) were aphakic.


The most common indication for IOL explantation has changed from ‘pseudophakic bullous keratopathy secondary to ACIOL’ to ‘PCIOL decentration or dislocation over the past 2 decades.’ These results reflect the changes in the surgical technique over the period. The second most common cause was endophthalmitis. Endophthalmitis has not been reported this frequently as a cause for IOL explantation in earlier studies. This is probably the first reported case series of IOL explantation from south-east Asia. Further analysis of the data will help us identify preventive measures needed to avoid IOL explantation.
